Chapter Two: Setting-Up the HOBO U14
Procedure
1.
Install Batteries
a.
Remove the battery door (back of unit).
b.
Insert the three AAA batteries. Make sure the batteries are installed in the proper direction.
2.
If you are using a Remote Alarm and/or Automatic Dialer, connect it to the HOBO U14 now (see page 17).
3.
Replace the battery cover.
4.
If you have an External Sensor model (002), plug the external sensor into the RJ-12 jack on the side of the HOBO U14. Hold the
black rubber flap down against the connector so it slides into the port.
NOTE
: The sensor readings will not be displayed until the logger is launched (immediate or delayed) or the status is checked using
either HOBOware or the U-Shuttle. The readings will not be logged until you launch the logger later in this procedure.
5.
Connect the U14 to a computer running HOBOware.
NOTE
: The U-Family logger requires a USB interface cable to connect to the computer (supplied with HOBOware software).
a.
Plug the large end of the USB interface cable into a USB port on the computer.
b.
Plug the small end of the USB interface cable into the side of the HOBO U14.
If the logger has never been connected to the computer before, it may take a few seconds for the new hardware to be detected
(Windows only).
c.
Run HOBOware.
d.
From the Main Menu, select
Launch
.
6.
Configure Launch Parameters. See the HOBOware User Manual or On-line Help for details on Launch parameters.
7.
Configure Alarms (page 8).
8.
Click on the Launch button to launch the HOBO U14.
NOTE
: If you remove the external sensor (002 model) after logging starts, you will need to relaunch the logger if you reconnect a
sensor.
9.
Disconnect the HOBO U14 from the computer by unplugging the USB cable.
10.
Transport logger to deployment site.
11.
Mount the HOBO U14.
The HOBO U14 is designed for a non-condensing, non-corrosive environment. Make sure the logger is installed in a location where
it will remain dry. Some of the external sensors can be placed in harsher environments (see the sensor manual for specifications).
a.
Mark the wall for the placement of the two mounting screws 2.5 cm (1 inch) apart (vertically).
b.
Screw in mounting screws, leaving a gap between the wall and the head of the screw of about 0.5 cm (3/16 in.).
c.
Attach logger by aligning it with the screws, and then push in and down to lock in place.
12.
If you have an External Sensor model (002), mount the External Sensors (see the sensor user manual).
In some applications (such as a refrigerator, freezer, clean room) it may be more convenient to permanently mount an external
sensor at the site. Be sure to place the remote sensor in a location that is representative of the target measurement location and
allows free flow of air (beware of any drafts caused by vents, doors, etc).
If you permanently mount the sensor and later have to disconnect it from the logger for readout, when you relaunch the logger select
Delayed Launch to allow time to reconnect the sensor before launch.
